Dotty's obviously doesn't need my review, but I'm adding it anyway! I recently visited during my first ever trip to Madison, and was instantly hooked. The fried cheese curds (a first for this East coast guy) were amazing, and the locals I was with mentioned that Dotty's were - in their opinion - the best in town.
A great selection of burgers, including buffalo and vegetarian options. I had the California burger with sprouts and guacamole, and unlike a lot of burger joints, the darn thing was actually cooked properly! When they said pink through the middle, they meant it. Halfway through the meal I stopped caring how messy I was getting. Oh, and as an added bonus, the service was friendly and reasonably prompt. I hope to be back one day....!
